12 beautiful pictures of mother and daughter in the animal world

The photos were taken by photographer Joel Sartore in his reportage project of captive animals in the world.

To implement this project, Sartore traveled to 40 countries and recorded images of more than 6000 animals in studio lighting and black and white backdrops to enhance the image's symbolism. His goal is no different than inspiring everyone not only to care about the natural world but also to help protect animals for future generations.
